Letters Patent No. 91,661, dated June 22, 1869.

MPROVEMENT IN CULTIVATORS.

The Schedule referred to in these Letters Patent and making part o'f the same.

To all whom 'it ma/y concern:

Be it known that we, R. B. PARKS and J. R. PARKS, .of Neponset, in the county of Bureau, and State of Illinois, have invented a new and improvedCnltivator; and we do hereby declare that the following is a full, clear, and exact description thereof', which will enable 'those skilled in the art to make and use'the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a new and improved cultivator, designed for cultivating crops grown in hills or It consists in a. peculiar' construction -and arrangement of parts, as hereinafter shown and described, whereby several advantages are'obtained, which will beset forth in the following description.

In the accompanying sheet of drawings- Figure 1 is a side sectional view of our invention, taken in the line a: x, fig.- 2'.

Figure 2, a transverse section of the same,`taken in the lineyy, fig.'l.

Figure 3, aplan ortop view of thesame...

Figure 4, an enlarged plan ortop View of a portion of the same.

Figure 5, a section of iig. 4, taken in the line z z.

Similar letters of reference indicate corresponding parts. Y

A represents a rectangular fname, which is secured` to an axle-bar', B, by means of clamps O, composed each 'of au angle-plate, a, having au oblong slot, b, through it, with notches c alluarouml, to receivea washer, d, provided with a '.lip, e, aj-bolt, D, passing through the side-piece f and washer d, with a nut, g,

on the inner ene of the bolt, at'the outer side of the washer, as shown moreparticnlarly in figs.l 4 and 5.

The angleplates a are tirmly secured to the axlebar B, by bolts or otherwise, aud it4 will be seen, that by loosening the nuts g, the trame A may be adjustedfulthe forward or backward, as may be required, in order to obtain a perfect balance,

E E are wheels, which are placed loosely on sepa# rate or independent arms F, firmly bolted to the ends ofthe axle-bar B; and

G is the drivers seat secured on the rear art of Y the frame A, the draught-pole H being secured to the ii'ont end. Y Y l I I represent two beams, which are suspended to the front and ,rear ends of the'i'rame A by joints h, so

constructed or arranged that the beams may swing laterally.

To these beams I I, the plow-standards .I are at# tached, two to each, and'at opposite sides of the beams.

These standards are curved, (see iig. 2,) sothat the shares of the'two standards of each` beam will be at a requisite distance apart.

To each beaml I, on the front part, there is attaehed a right-angular, or L-shaped lever, K, the lower arms of which are connected, by chains L, to

treadles M M, the front ends of said treadles being connected by joints t to the front part of flame A. (See iig. 1.) i l 4 The upper arms of the levers K K are connected by bars j k, one of which, j, has asector-rack, N, se-

cured to its inner end, with a'lever, 0, attached, saidY v lever being connected with the other bar k, as shown at l, and having a pendent lip, m, at its. under side,

to' catch into the rack N at any desired point,

By this arrangement, it will be seen,- that by ad justing the lever O, the sharesof the standards attached to the two beams may be-set at a greater or less distance from the plants, as desired, and at any time when the machine is 'in motion or at work.

The standards J are secured to the beams I I by means of pivots a, which admit of the standards being freely raised and lowered, the standards being connected by chains o to the lower ends of levers KX,

which are secured to the beams;

The upper ends of these levers K are connected, by rods Q, to upright levers R, ,at the rear parts ot' the beams I I, and rthese levers R, byv means of .semicircular racks S, may be secured at any point within the `scope of their movement.

This arrangement admits ofthe shares being adjustedhigher or lowes-as desired, and also of being raised entirely above the ground,.when desh'ed, without the necessity of raising the beams.

It will be seen, that by vibrating the beams I, either or both of them, the shares may be madeto 'conform to the sinuosities of thev rows of plants, and

eitheror both voi the beams may be elevated more or less, as required, to make the shares eontbrm to the *inequalities of surface overwhich they may pass.

lhismaehinelas a whole, i,s extremely simple and .eicient, and may-be readily A managedl by the driver, for workin'g'either on level or undulating land.

XVe claim as new, and desire to secure by Letters Patent- '1. The suspended beams I I, with plow, or sharestandards J attached, in combination with the levers K, connected 4by the rack N and lever O, ali arranged and combined to operate in the manner substantially as and for the purpose set i'orth.

2. Securing the i'rame A to 'the axle-bar B, by means ot' the clamps C, constructed and arranged as shown, so as to admit of the ready adjustment ofthe frame A, in amore forward or backward direction, as may be required.

with a cultiva-tor, substantially as and for the purposes described.

The above specificationof our invention signed by ns, this 28th day ot' September, 1868.
